“…Recently, the initial surgical technique has been modified with the use of radiofrequency ablation. 6,7 Although MAZE offers successful long-term elimination of AF, the precise effects on LA size and mechanical function remain unclear. This is attributed mainly to the limited methodological means to accurately evaluate LA geometry and wall motion.…”

Background-Although the MAZE procedure allows for the recovery of sinus rhythm and left atrial (LA) mechanical function in the great majority of patients with chronic atrial fibrillation (AF), the effects of MAZE on the precise LA geometry and wall motion remain to be elucidated. We hypothesized that LA size and mechanical function in patients with chronic AF and mitral valvular disease are well restored after MAZE. In the CABG group, LA maximal and minimal volumes and ejection fraction were 109Ϯ12 mL, 82Ϯ11 mL, and 26Ϯ10%, respectively. In the MAZE group, LA maximal volume was 139Ϯ17 mL (Pϭ0.187 versus CABG), and LA minimal volume was 121Ϯ16 mL (Pϭ0.082 versus CABG), with an ejection fraction of 15Ϯ7% (Pϭ0.004 versus CABG). In both groups, all parts of the LA wall contracted toward the geometric center of the LA. The extent of wall motion was significantly worse in the MAZE group compared with the CABG group. In both groups, LA booster function was inversely correlated with LA maximal volume. Conclusions-MAZE

“…Cox-maze procedure has been the most commonly performed surgical treatment for long lasting permanent atrial fibrillation (7,(14)(15)(16). Despite its impressive results in treating AF; this procedure significantly lengthens both the cross-clamp and operation times, it increases the postoperative bleeding risk, and can be performed only by experienced surgeons (14)(15)(16).…”

“…Despite its impressive results in treating AF; this procedure significantly lengthens both the cross-clamp and operation times, it increases the postoperative bleeding risk, and can be performed only by experienced surgeons (14)(15)(16). For these reasons Cox-Maze-III procedure can only be performed in definite cardiac centers.…”

“…The success of the procedure in reported series is about 80-95% (7)(8)(9)(10)(11)(12)(13)(14)(15). But this procedure significantly lengthens both the cross-clamp and operation times, and increases the postoperative bleeding risk (16). As a result Maze procedure can only be performed at definite cardiac centers by experienced surgeons.…”

“…However it was first used intraoperatively by Melo et al (21), and today it has been performed widely in many centers. Early and midterm results were found as successful as Maze procedure (14)(15)(16)(17)(18)(19)(20)(21). After the definition of the technique, many modifications of the procedure and new ablation catheters were studied and many studies are still continuing in many centers.…”

CERRAHİ BİLİMLER / SURGICAL SCIENCES Araştırma Makalesi / Research ArticleGiriş: Bu çalışma, profilaktik amiodaron tedavisinin intraoperatif radyofrekans ablasyonunun sonuçları üzerine etkisini değerlendirmek amacıyla planlandı. Hastalar ve Yöntem:İntraoperatif radyofrekans ablasyonu uygulanmak üzere seçilen 80 hasta bu çalışmaya katıldı ve bu hastalar 2 gruba randomize edildi: ilk grup operasyondan önce 24 saat sü-reyle 30mg/saat amiodaron alırken, 2. gruba plasebo verildi. Klinik çıktılara ek olarak kalp hızları ve kalp ritmi hastanede kalım süresince ve 1. ayın sonunda kaydedildi. Bulgular:Demografik ve kardiyak bulgular her iki grupta da benzerdi. Her ne kadar hastaneye yatırılma sırasındaki kalp hızları benzerse de (102,07±16,04 amiodaron grubu için ve 99,17±17,23 kontrol grubu için, p=0,477), anestezi indiksüyonu (83,17±11,77, p<0,001) ve taburculuk sırasında (79,83±10,08, p=0,012) kalp hızları amiodaron grubunda anlamlı olarak düşük bulundu. Hastaneye yatırılma sırasında ve anestezi indiksiyonunda bütün hastalar atriyal fibrilasyondaydı. Radyofrekans ablasyonu sonrası amiodaron grubundaki 31 (77,5%) hasta ve kontrol grubundaki 29 (72,5%) hasta sinus ritmindeydi, aradaki fark anlamlı değildi (p=0,770). Birinci ayın sonunda kalp hızları (83,91±9,11 amiodaron grubu için ve 86,41±9,31 kontrol grubu için, p=0,671) ve sinus ritmindeki hasta sayısı (amiodaron grubunda 29, kontrol grubunda 28 hasta, p=1) gruplar arasında benzerdi.Tartışma: Preoperatif amiodaron kullanımı kalp hızında operasyondan önce ve sonra anlamlı düşüş kaydetmekle beraber, radyofrekans ablasyonunun başarı oranını değiştirmemektedir. Anahtar Sözcükler: Atriyal Fibrilasyon, Mitral Kapak, AritmilerObjectives: This study was designed to evaluate the effects of prophylactic amiodarone infusion on the outcomes of intraoperative radiofrequency ablation.Design: Eighty patients who were scheduled for intraoperative radiofrequency ablation were enrolled in this study and randomized into two groups: first group received 30mg/h amiodarone 24 hours before the operation, and the second group received placebo. Heart rates and cardiac rhythms in addition to clinical outcomes were measured during hospitalization and at the end of the 1 st month. Results:The demographic and cardiac data were similar in both groups. Although the heart rates at the time of admission were similar between groups (102,07±16,04 for amiodarone group and 99,17±17,23 for control group, p=0,477), they were significantly lower in the amiodarone group at the time of anesthesia induction (83,17±11,77, p<0,001) and discharge (79,83±10,08, p=0,012). All the patients in both groups were in AF at the time of admission and anesthesia induction. Following RFA 31 (77,5%) of the patients in the amiodarone group and 29 (72,5%) of the patients in the control group were in NSR, and the difference was insignificant (p=0,770). At the end of the first month the mean heart rates (83,91±9,11 for amiodarone group and 86,41±9,31 for control group, p=0,671) and the number of patients in NSR (29 patients in ...
